I have an early 4l60e , 4 bolt rear extension housing, that i am adapting to a dana 20. I have received the adaptor kit , part no. 172-e.
My question is where does the transmission speed sensor mount. I noticed that the later 4l60e adaptor kit has a longer extension housing that looks to house the speed sensor.
Is there a similar extension housing to suit the 4 bolt 4l60e?
